CUTTER-BAR FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 244,435, dated July 19, 1881.

- Application filed April 16, 1881. (No model.)

To all whom "it may concern:

Be it known that I, PHILLIP CHANNING CREEs, of the county of Decatur and State of Iowa, have invented certain new and useful 5 Improvements in Gutter-Bars for Harvesters; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same,

1 reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification, and

in which--- Figure 1 is a plan view of my improved cut- 1 ter-bar for harvesters. Fig. 2 is a similar View, with the individual cutters wholly exposed;

I and Fig. 3 is a detailed View thereof.

This invention appertains to improvements in cutter-bars for harvesters of that class having a series of separatecutting-teeth, each adapted to be removed for sharpening or for other purposes, havingfor its object to provide for the ready removal and replacing of the teeth and the holding in a readily-removable manner of the end-securin g or false tooth; and it consists of the detailed construction of the individual teeth, and in certain other features, substantially as hereinafter more fully set forth and claimed.

Referring to the accompanying drawings, A A indicate two parallel bars, the under; neath one having one end turned up and lapped over the upper one, as at a. The overlapping portion a has an eye, a, to adapt it, in connection with a hook or pintle, to be hinged or pivoted to the harvester. The underneath bar, A, has a series of cleats or separating-plates, b, arranged at intervals apart according to the width of the teeth, as seen. in Fig. 2.

40 B B are the cutters, in the form of teeth, tapering each to a point central with its width, as is well known in the art. The sides of the tooth at the base of its sloping edges are parallel, as at c, which fit snugly between two of the cleats b. One-of the side edges of the tooth is inclined inwardly a shortdistance, as at c, and thence extended again straight, as at 0 The opposite side of the tooth is inclined from a point a little higher up than thepoint of com- 50 mencement of the incline on the other side,

outwardly about twice the distance as the incline c, as at 0 and thence again extended straight, as at a, slightly greater than the op posite edge, 0

B is a blunt or false tooth, of somewhat 5 5 modified construction, with a corresponding extension, 0 12 and a projection or extension, 0, on its other side.

It will be noticed that by consulting Fig. 2,

with the teethplaced imposition as therein shown, the inserting of the teeth being conducted by commencing with the tooth at the outer end of the bar and ending with thetooth B, each tooth will serve to mutually secure the other in position between the bars A A and the cleats 1) without the aid of other fastenin gs-,or the passing of fastenin g-bolts through the teeth themselves. The advantage of this arrangement is to permit of the ready removal and replacing of the teeth for sharpening, renewal, orother purpose. The plate A is bolted to the underneath plate after the insertion of the teeth. A spring-plate, G, with one end fastened to the bar A, and its other end provided with an angular aperture, 0 is adapted, 7 5 by springing it over the nut upon the bolt passin g through the lapping portion a of the said bar, to prevent the nut turning by jarring or concussion.

Having thus fully described my invention, I claim and desire to secure by Letters Patent The combination, with the parallel plates or bars A A, the plate A provided with the cleats or partitions b, of the teeth B B, the

teeth B having the inwardly-inclined surface, 8 5.

c, and made straight above and below the incline, as at c and 0 on one side, and provided with the greater outward inclination, c and above and below this inclination with a straight surface, 0* and 0 on the other side, and the tooth B having on each side an outwardlyinclined extension, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two 5 witnesses.

PHILLIP OHANNINGGREES.
